Core Viewpoint - The debate surrounding Yi Huiman's tenure highlights the duality of his impact on the A-share market, with criticisms focusing on excessive IPOs draining liquidity, while others emphasize the positive reforms such as the introduction of the registration system and new delisting rules that have made the market more accessible and healthier [1][2]. Group 1: Regulatory Changes - The new Securities Law introduced in late 2019 established a registration system, while the delisting rules published in 2021 mandated automatic delisting for non-compliant companies [2]. - The penalty for fraudulent listings was significantly increased from a maximum of 600,000 to double the amount raised through the fraudulent activities, which could lead to severe financial consequences for offending companies [2]. Group 2: Market Dynamics - The historical issue of A-shares being a one-way market has led to many quality companies seeking listings abroad, while the previous lenient delisting rules allowed many poor-quality companies to remain listed [1][2]. - The backlog of companies waiting to go public has negatively impacted investors, but the overall quality of these companies is expected to benefit the A-share market in the long run [2]. Group 3: Case Study - Zijing Storage - Zijing Storage faced severe penalties for financial fraud, including inflating revenue and profits through fictitious sales contracts and other deceptive practices, resulting in a total fine of 90.71 million yuan for the company and its executives [6][16]. - The company’s fraudulent activities included inflating revenue by 43.5 million yuan in 2017, 111.46 million yuan in 2018, and 66.94 million yuan in the first half of 2019, with profit inflation percentages reaching as high as 150.21% in 2020 [7][8][9][13][14]. Group 4: Investor Compensation - The Zijing Storage case marked a significant milestone in A-share history with the introduction of a proactive compensation mechanism, allowing for early compensation to investors amounting to approximately 1.086 billion yuan [17][19]. - The case established new practices such as the administrative enforcement commitment system and representative litigation, which aim to protect investor rights and enhance regulatory efficiency [21][22][23].
